The invention provides a data modeling method for full information data archives of traffic objects. From specific road network environments and data acquisition environments of the traffic industry, an object-oriented data modeling method is provided by performing single data resource organization mode-oriented comprehensive sorting and modification on a relational database, a data warehouse and the like; based on identification, objectification and ontology creation of three major traffic main bodies including pedestrians, vehicles and roads, object metadata, data addresses, outer objects and inner objects are integrated to form a standard object atomic model, and networking is performed to form data crystals; and traffic big data platform integrated environment and data open construction is supported.
